Read/write
The voltage/temperature channel ADC control MMR is a 16-bit register that is used to configure the V/T-ADC. If
both ADCs are being reconfigured, ADC1CON should be written before ADC0CON to ensure both ADCs start
synchronously. If ADC0 is already on and converting and ADC1 is off, then, first turn on ADC1 and second disable,
and re-enable ADC0 so that the two ADCs start simultaneously (this accounts for ADC start-up time).
Description
Voltage/temperature channel ADC enable.
This bit is set to 1 by user code to enable the V/T-ADC.
Clearing this bit to 0 powers down the V/T-ADC.
VTEMP current source enable.
0, 0 = current sources off.
0, 1 = enables 50 μA current source on VTEMP.
1, 0 = enables 50 μA current source on GND_SW.
1, 1 = enables 50 μA current source on both VTEMP and GND_SW.
Not used. These bits are reserved for future functionality and should not be modified by user code.
Voltage/temperature channel ADC output coding.
This bit is set to 1 by user code to configure V/T-ADC output coding as unipolar.
This bit is cleared to 0 by user code to configure V/T-ADC output coding as twos complement.
Not used. This bit is reserved for future functionality and should be written as 0 by user code.
Voltage/temperature channel ADC input select.
0, 0 = VBAT/24, AGND. VBAT attenuator selected.
0, 1 = VTEMP, GND_SW. External temperature input selected, conversion result written to ADC1DAT.
1, 0 = internal sensor. Internal temperature sensor input selected, conversion result written to ADC1DAT. The
temperature gradient is 0.33 mV/°C; this is only applicable to the internal temperature sensor.
1, 1 = internal short. Shorted input.
Not used. This bit is reserved for future functionality and should be written as 0 by user code.
Voltage/temperature channel ADC reference select.
0 = internal, 1.2 V precision reference selected.
1 = (REG_AVDD, GND_SW)/2 selected.
Not used. These bits are reserved for future functionality and should not be written as 0 by user code.
